USECURLIB

Controls use of the ODBC's Cursor Library.

The Cursor Library can provide support for scrolling cursors when the underlying driver doesn't, and can also allow "simulated" positioned updates. With USECURLIB=YES, the Cursor Library will always be used. With USERCURLIB=NO, it will never be used. With the default USERCURLIB=IFNEEDED, it will be used if the application tries to do something the driver manager thinks the driver doesn't support. To use a scrolling cursor with the Cursor Library, you must use a STATIC cursor. To do positioned updates using the Cursor Library, you must use OPTCCVAL concurrency.

Note: A "simulated" positioned update might hit more than one row. We recommend including the primary key in the select for this reason.

Syntax:

USECURLIB={NO | YES | IFNEEDED}
NOUSECURLIB

Properties:

Default: USECURLIB=IFNEEDED

Scope:

Used at compile time: No
